Sistem capaian berbilang pembahagian kod berbilang pembawa (MC-CDMA) sangat sesuai untuk perkhidmatan multimedia tanpa wayar kadar data tinggi, kerana keupayaannya untuk menukar saluran pudar selektif frekuensi kepada saluran pudar rata yang berbeza dengan peranti transformasi Fourier pantas (FFT) yang kompleksiti rendah. Walau bagaimanapun, apabila berbilang pengguna hadir, prestasi sistem MC-CDMA dirosotkan oleh gangguan berbilang pengguna (MUI) apabila saluran adalah selektif frekuensi. Untuk mengurangkan MUI, kami mempersembahkan algoritma bersama yang menggabungkan kawalan kuasa penghantaran, pemprosesan tatasusunan antena dan pengesanan berbilang pengguna pada penerima. Menariknya, selektiviti frekuensi yang melibatkan MUI juga menyediakan kepelbagaian berbilang laluan yang boleh membantu menekan MUI. Prestasi algoritma dalam beberapa model sistem MC-CDMA dinilai dari segi kuasa penghantaran purata untuk mencapai isyarat sasaran kepada gangguan campur nisbah hingar (SINR). Simulasi mengesahkan prestasi cemerlang algoritma ini berbanding dengan yang sedia ada dalam sistem MC-CDMA.

Abstract: Multicarrier code division multiple access (MC-CDMA) systems are well suited for high data rate wireless multimedia services, due to their ability to convert frequency-selective fading channels to distinct flat fading channels with low complexity fast Fourier transform (FFT) devices. However, when multiple users are present, the performance of MC-CDMA systems is degraded by the multiuser interference (MUI) when the channel is frequency-selective. In order to mitigate MUI, we present a joint algorithm that combines transmit power control, antenna array processing and multiuser detection at the receiver. Interestingly, the frequency-selectivity that entails the MUI also provides multipath diversity which can help suppress the MUI. Performance of the algorithm in a number of MC-CDMA system models is evaluated in terms of the average transmit power to achieve the target signal to interference plus noise ratio (SINR). Simulations confirm the outstanding performance of this algorithm compared with the existing ones in MC-CDMA systems.
